[0015] (1) After the sampling component provided in the present invention is controlled by the control component to complete the sampling, the sample classification can be carried out through the partition component, and the samples of different depths can be taken out and stored separately. When using the partition component, all the sampling tubes are first taken out through the fixed rod of the control block, and then the sampling tube that needs to be segmented is selected, and the dial plate on the outer side of the adjustment disk at the bottom of the sampling tube is controlled to make the two electromagnets magnetically swapped, so that the dial plate drives the adjustment disk to rotate in the isolation sleeve until the partition plate completely blocks the circular hole opened in the center of the adjustment disk and the isolation sleeve. At this time, the soil sample in the sampling tube is separated from other soil samples at its bottom. At this time, the locking component can be unlocked to separately take out the sampling tube corresponding to the required soil sample depth, thereby improving the work efficiency of the staff and enhancing the use effect of the device.

[0016] (2) The positioning assembly provided in the present invention can release the connection between adjacent but unconnected sampling tubes and isolation sleeves during the driving process of the partition assembly. When the paddle plate moves, the moving sleeve provided at the bottom end of the paddle plate will drive the positioning rod and the sliding column to move. Since the sliding column is stuck in the arc groove opened at the bottom end of the isolation sleeve, when the paddle plate moves to cause the partition assembly to isolate the soil sample, the sliding column will slide along the arc groove to a position away from the axis of the sampling tube. At this time, the positioning rod connected to the outside of the sliding column by the elastic rope will be pulled out of the positioning groove. At this time, the first spring is compressed, and the connection between the two adjacent sampling tubes and the isolation sleeves is released.

[0017] (3) The locking assembly provided in the present invention can simultaneously release the locking relationship between the isolation sleeve and the sampling tube at its bottom when the test personnel are taking samples, thereby avoiding accidental movement between the isolation sleeve and the sampling tube and reducing the operating steps of the test personnel. When it is necessary to remove the isolation sleeve and the sampling tube at the top thereof, the two pull rings can be pulled up to move the connecting block at the bottom of the pull ring upward. At this time, the second spring provided between the top of the connecting block and the inner connecting plate is compressed. At the same time, the traction rope provided at the bottom of the connecting block will slide along the guide wheel, so that the traction rope pulls the insertion rod to move along the clamping sleeve until the insertion rod is disconnected from the fixed sleeve. At this time, the isolation sleeve is disconnected from the sampling tube at its bottom, and the isolation sleeve and the sampling tube can be removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments:

[0026] Example:

[0027] like Figures 1 to 6 As shown, the present invention provides a stratified sampling device for soil environment detection, including a control component and a sampling component, the control component is connected to the hydraulic pump station through a line, the sampling component includes a drilling tube 6, the bottom end of the drilling tube 6 is screwed with a drill bit 1, a plurality of sampling tubes 9 are arranged inside the drilling tube 6, and a partition component is arranged at the bottom end of each sampling tube 9, the partition component includes an isolation sleeve 34 coaxially connected to the bottom end of the sampling tube 9, an adjusting disk 39 is rotatably provided in the isolation sleeve 34, a guide block groove 37 is provided on the adjusting disk 39, and a plurality of sliders 38 are slidably provided in the guide block groove 37, each slider 38 is fixedly connected to a partition plate 36 at the top end, a slide button 35 is provided on the partition plate 36, a plurality of guide plates 30 are connected to the top end of the isolation sleeve 34, each guide plate 30 is provided with a guide groove 33, and the slide button 35 is slidably provided in the guide groove 33.

[0028] like Figure 2 and Figure 6 As shown, a dial plate 31 is connected to the outside of the adjustment disk 39 , and the dial plate 31 is slidably clamped in a control slot 32 opened in the isolation sleeve 34 . Magnetic blocks are arranged at both ends of the control slot 32 , and electromagnets are arranged at both ends of the dial plate 31 .

[0029] After the sampling component is controlled by the control component to complete the sampling, the sample classification can be carried out through the partition component, and the samples of different depths can be taken out and stored separately. When using the partition component, all the sampling tubes 9 are first taken out through the fixing rod 16 of the control block, and then the sampling tube 9 that needs to be segmented is selected, and the dial plate 31 on the outer side of the adjustment disk at the bottom of the sampling tube 9 is controlled to make the two electromagnets magnetically swapped. Through the magnetic force of the electromagnet and the magnetic blocks at both ends of the control slot 32, the dial plate 31 drives the adjustment disk to rotate in the isolation sleeve 34. Since the sliding card is provided in the guide block slot 37 opened on the adjustment disk The top of the slider 38 is fixedly connected with a partition plate 36, and the sliding button 35 provided on the partition plate 36 is clamped in the guide groove 33 provided on the guide plate 30 at the top of the isolation sleeve 34. Therefore, the rotation of the adjusting disk will drive the partition plate 36 to move until the partition plate 36 completely blocks the circular hole provided in the center of the adjusting disk and the isolation sleeve 34. At this time, the soil sample in the sampling tube 9 is separated from other soil samples at its bottom. At this time, the locking assembly can be unlocked to separately take out the sampling tube 9 corresponding to the required soil sample depth, thereby improving the work efficiency of the staff and enhancing the use effect of the device.

[0030] like Figure 5 and Figure 6 As shown, a positioning assembly is provided at the bottom end of the dial plate 31, and the positioning assembly includes a movable sleeve 29 provided at the bottom end of the dial plate 31, a positioning rod 25 is slidably clamped at one end of the movable sleeve 29, a positioning sleeve 23 is provided at the top end of the sampling tube 9, a positioning groove 24 is opened on the positioning sleeve 23, the positioning rod 25 is slidably clamped in the positioning groove 24, and the free end of the positioning rod 25 is connected to the inner wall of the movable sleeve 29 through a first spring 27.

[0031] like Figure 5 As shown, a sliding column 28 is slidably mounted in the movable sleeve 29 , and the outer side of the sliding column 28 is connected to the free end of the positioning rod 25 through an elastic rope. An arc groove 26 is opened at the bottom end of the isolation sleeve 34 , and the sliding column 28 is slidably mounted in the arc groove 26 .

[0032] The positioning assembly can release the connection between the adjacent but unconnected sampling tubes 9 and the isolation sleeve 34 during the driving process of the partition assembly. When the paddle plate 31 moves, the movable sleeve 29 arranged at the bottom end of the paddle plate 31 will drive the positioning rod 25 and the sliding column 28 to move. Since the sliding column 28 is stuck in the arc groove 26 opened at the bottom end of the isolation sleeve 34, when the paddle plate 31 moves to make the partition assembly isolate the soil sample, the sliding column 28 will slide along the arc groove 26 to a position away from the axis of the sampling tube 9. At this time, the positioning rod 25 connected to the outside of the sliding column 28 by the elastic rope will be pulled out of the positioning groove 24. At this time, the first spring 27 is compressed, and the connection between the two adjacent sampling tubes 9 and the isolation sleeve 34 is released.

[0033] like Figure 5 and Figure 6As shown, a locking assembly is provided at the bottom end of the isolation sleeve 34, and the locking assembly includes a fixed sleeve 13 arranged on the outer side of the top end of the sampling tube 9, and a clamping sleeve 15 is provided at the bottom end of the isolation sleeve 34.

[0035] The locking assembly can simultaneously release the locking relationship between the isolation sleeve 34 and the sampling tube 9 at its bottom when the experimenter is taking samples, thereby avoiding accidental movement between the isolation sleeve 34 and the sampling tube 9 and reducing the operation steps of the experimenter. When it is necessary to remove the isolation sleeve 34 and the sampling tube 9 at its top, the two pull rings 19 can be pulled up to move the connecting block 18 at the bottom of the pull ring 19 upward. At this time, the second spring 17 arranged between the top of the connecting block 18 and the internal plate 20 is compressed. At the same time, the traction rope 21 arranged at the bottom of the connecting block 18 will slide along the guide wheel 22, so that the traction rope 21 pulls the insertion rod 14 to move along the clamping sleeve 15 until the insertion rod 14 is disconnected from the fixed sleeve 13.
